The notion of arachnid extinction is really absurd. First, they are more your friend, than your enemy, and without them humans could not exist. The planet would be dominated by insects.
The population of spiders outweighs the population of humans on this planet, and if every human killed a thousand spiders a day, you would not rid spiders from earth.
Whoops - did I somehow log in to the sixteenth century? Do we seriously need to explain that the theory of spontaneous generation is wrong? I would tell you about the shape of the world, but I worry I might completely blow your mind.
This is illogical.
If you kill all of them before they lay eggs, then yes, they will be extinct.
Or spiders can still come from trees or any plants that produce spiders even if it was possible to exterminate all and every single one of them? Even if they are all different in all countries.
